låta bli

låta bli

1. avoid, restrain oneself from, keep from; usually with respect to touching, meddling with, or generally doing

   Låt bli saxen! Den är ingen leksak.

   Don't touch the scissors! They are no toys.

Always refers to an action which should be avoided, though the action may be implicitly understood. For example in the example above, the action referred to is "röra" (=touch). If one wants to specify the action to be avoided, it is to follow in the full infinitive, as in Låt bli att röra saxen!.
